== System Wide Changes ==
* Modular Kernel Packaging for Cloud
   URL: ​​​
    Announcement: ​ 

Kernel modules that are not necessary in virtualized environments become 
optionally (un)installable. 

* Optional Javadocs

Make javadoc subpackages of Java packages optional in guidelines and 
communicate this change to users. 

* Ruby on Rails 4.1
  URL: ​

* Java 8 
  URL: ​
  Announcement: ​ 

Make Java 8 (provided by OpenJDK 8 which is java-1.8.0-openjdk) the default 
Java runtime. The current default Java runtime (Java 7, provided by OpenJDK 7, 
java-1.7.0-openjdk) will be obsoleted and removed.

This is essentially an upgrade to the latest Java and OpenJDK version. 

* PrivateDevices=yes and PrivateNetwork=yes For Long-Running Services
  URL: ​​
  Announcement: ​ 

Let's make Fedora more secure by default! Recent systemd versions provide two 
per-service switches PrivateDevices?=yes/no and PrivateNetwork?=yes/no which 
enable services to run without access to any physical devices in /dev, or 
without access to kind of network sockets. So far this has seen little use in 
Fedora, and with this Fedora Change we'd like to change this, and enable these 
for all long-running services that do not require device/network access. 

notting has question to note: is disconnecting the netlink and audit namespace 
truly required, or just merely a choice of what they decided to remove? 

== Self Contained Changes ==

discussed at ​ 

Amplab-Tachyon is a fault tolerant distributed file system enabling reliable 
file sharing at memory-speed across cluster frameworks.

* Apache Mesos - ​ discussed

This change brings Spark to Fedora, allowing easy deployment and development 
of Spark applications on Fedora.

Fedora now supports several essential parts of the Scala language ecosystem as 
well as building packages with sbt, the de facto build tool for the Scala 

Scala proposal owners to work to develop packaging guidelines

* DNSSEC support for FreeIPA - ​ discussed at ​ 

FreeIPA with integrated DNS server will support serving of DNSSEC secured 
zones and automatic DNSSEC key maintenance.

This first version will have only the very basic functionality with limited 
user interface and limited resiliency. Next versions (to be delivered in 
Fedora 22 time frame) will improve resiliency and user interface 

* NFS Ganesha File Server - ​ 
discussed at ​ 

NFS Ganesha is a user mode file server that supports NFSv3, NFSv4, and NFSv4.1

= Rejected Changes =
* Security Policy In The Installer
  URL: ​
  Announcement:  ​

There are many known tips and tricks how to make a system more secure, often 
depending on the use case for the system. With the OSCAP Anaconda Addon and 
the SCAP Security Guide projects, we may allow users choosing a security 
policy for their newly installed system. 

Please consider re-proposing as a kickstart-only change.
